Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an accelerator lake that is added to an existing process combination coke to increase its processing capacity.

[Conventional technology]

As a control device for controlling the process, an industrial mini-computer, a so-called process combination computer, is used for boat fishing. Then, the program is created using the program development support function and executed using the processing device in the program execution environment.

In addition, the processing capacity of a process computer is designed based on the amount of processing steps of the control model and the control cycle for executing it, so it is extremely difficult to add a new control model to an existing process combination coke. In such cases, the methods of simplifying the control model or installing a new process computer are adopted.

[Problem to be solved by the invention]

However, the process combi coke having the above-mentioned characteristics has the following three drawbacks.

Firstly, a processing device, a
Since program execution environments such as operating systems (operating systems) and program development support functions have different structures, they are not compatible and are extremely inefficient when applying one control model to multiple processes.

Second, adding a large amount of processing steps requires the installation of a new process computer, which is extremely costly.

Third, in order to modify and launch a processing program on an existing process computer, it requires a great deal of effort to investigate, modify, and test the existing program, and it is also necessary to stop the process computer for testing. This will have a negative impact on operations, such as a decline in performance.

Therefore, the problem to be solved by the present invention is that when adding new processing capacity to an existing process computer, it is not affected by the type of process combi coater, the processing program is highly compatible, and the processing capacity can be easily adjusted. In addition, it is possible to minimize modification of existing process computers.

[Means for Solving the Problems] In order to solve the above problems, the accelerator of the process combi coater of the present invention has a transmission function for inputting and outputting information to and from a process computer, and a transmission function for inputting and outputting information from the process computer to process the information received from the process computer. It has an integrated processing unit that has an information distribution and transmission function for distributing and transmitting information to a high-speed parallel processing device installed correspondingly, a development support function for a program to be executed on the high-speed parallel processing device, and an operator input/output function such as a keyboard and a display device. The high-speed parallel processing device is equipped with an information distribution and transmission function that distributes and transmits the information received from the information distribution and transmission function to the corresponding high-speed processing device, and a plurality of high-speed processing devices that process the received information at high speed. It is characterized by

The number of high-speed parallel processing devices described above can be installed as many as necessary depending on the required execution time.

[Effect]

In the present invention, in response to a program execution request from a process combicoater, an integrated processing device distributes and transmits information to a high-speed parallel processing device that executes information processing. The high-speed parallel processing device performs high-speed processing of programs and transmits the processing results to the process computer via the central processing device.

In this way, since the central processing unit and high-speed parallel processing unit only send and receive information to and from the process combi coater, modification of the existing process computer requires the minimum operation of adding communication software. That's all,
The impact on operations is small.

Furthermore, it is not affected by the type of process combi coater and has high compatibility of processing programs. Moreover, the processing capacity can be easily adjusted according to the amount of processing steps of the control model.

The number of steps 3 can be determined depending on the total number of steps and the required execution time, resulting in a highly flexible system configuration.

FIG. 2 is a block diagram showing the hardware configuration of the embodiment of the present invention.

The central processing unit P1 uses an existing personal computer as a host CPU, and freely calls and executes the processes registered in advance in the transputer (product name) Trρ #1 to 8 of the processing unit P3, which serves as a slave CPU. This is what makes it possible. This system and the process computer 1 are connected using a standard interface.

As a transputer, the processing speed is IOMIPS
High-speed parallel processing is performed using a link with a link speed of 20 Mbit/sec.

The process on the host PC 2 side and the process on the transputer 4 side are executed independently, and the post PC 2 receives only the execution result of the started process on the transputer 4 side and performs necessary processing. Moreover, the transputer 4 is
By connecting each other with serial links, parallel CP

■ Process startup request [EN()] from PC2 (host)
and process ID [procid].

■ The transputer side checks the rationality of the data received from the post PC 2 and returns a refresh code.

■ If there is no abnormality in the process activation request from the host PC 2, linkage data is passed to the relevant process and the process is activated.

■ Upon completion of the process, a request is made to the host PC2 (activating the INT port of the data bus of the host PC), and a reception request is sent to the host PC2 [
ENQ+proc+d]. In reality, when data is accepted into the data buffer of the link adapter on the root transputer board in Figure 2,
An interrupt is sent to PC2.

(2) When a response of reception ΔCK (M acknowledgment signal) is returned from the host PC2, data indicating the completion of the process is sent to the host PC2. If the response is NAK (not received), write IJ after a certain period of time.

- A return code is sent from the host PC 2, and if it is normal (-0), the process ends. Return code≠
If it is 0, an error code is sent to the host PC2.

In this case, boss PC2 sets an error flag.

Note that each process of the transputer does not necessarily terminate in the order in which it was started.
